Struct clippy_utils::mir::possible_origin::PossibleOriginVisitor
source · pub(super) struct PossibleOriginVisitor<'a, 'tcx> {
possible_origin: TransitiveRelation,
body: &'a Body<'tcx>,
}
Expand description
Collect possible borrowed for every &mut
local.
For example, _1 = &mut _2
generate _1: {_2,…}
Known Problems: not sure all borrowed are tracked
Fields§
§possible_origin: TransitiveRelation
§body: &'a Body<'tcx>
